Former Manchester United striker Andy Cole insists Alexis Sanchez didn’t become a bad player overnight and expects he will improve under Ole Gunnar Solskjaer

Sanchez has only scored four times in 32 appearances for United since completing his transfer from Arsenal last year.

This marks quite a drastic turnaround from the stunning form he showed at the Emirates Stadium with Sanchez finding the net 80 times in 166 games at Arsenal.

“You never become a bad player overnight,” Cole told ESPN.
